Be it known thatI, SAMUEL H. HoGG'soN,

' a citizen of the United States, residing atjthe city of New' York, borough of Manhattan, in

thecounty and State of New York, have in- .i vented certain new and useful Improvements sin Electromechanical Clocks, of which the following is a full, clear, and exact specification.

. My invention relates -to improvements in, motors for actuating divers forms of machin- 'erygand said invention has for its object more particularly1 to provide a simple, efficient, and positiveelectromechanical apparaf4 tus for operating clockwork, and analogous machines. i 1 l.

The objects above enumerated I am enabled to attainV by meansof my invention,.

which consists in the novel details of constructionand in thecombination,connection, andI arrangement of parts, as' hereinafterl more fully described and then pointed'pout in the.

claims.

In the accompanyingv drawings, forming a part of this specification, wherein like letters of referenceindicatelike,parts,'Figure l is a Fig. 2 is a side 'view thereof. Fig. 3 is acenitral lsection vof the solenoid, and Fig. 4 is a ldetail perspective view ofthe main' actuating-' Insaid drawings, A designates the clock-` frame, consisting ofthe plates 'Af A2, conf nected together adjacent to. their upper ends by the pillariB, having aisplit end which 'exa bracket B', having fahorizontal projecting portion B2, provided with an aperture to permit of the passing f'thejarrnature Iof -the soflenoid therethrough.A 'y

Upon thebracket B"v isl secured i' a solenoid ),'inclosed by a soft-steeljacketC .and hav# ing a ho'llow'brasscore 'O2 within which Works'the armature D, provided atfits 'low-er.. projecting end with a rubber (washer or cushf other terminal E2 of saidsolen'oid is con?y vnected tol the'hollow brass core C2, and upon the insulatedportien'ofthe terminal E, ad-

posed a seriesot' convolu 'ons of wire G, one

end of which is connecte to the terminal E Within the;fraine,A,-near its middle, is.

jou rnaled a main drivin g-shaft'H-,having fixed vjacent to the top of thefsolenoid-G, aredisthereon near its rear end,- butfwithin them-' frame, a pinion' H andagear-wheelI-I2, and znear the vforward end of saidv shaft is disposed. thebifurcated end of a lever I, between 'which is fixed' a ratchet-wheeliHS. l

SI denotesa spring-detenta having` oneend secured to the outer 'end ofthe leverv I and its other end iniengageinentfwith 'the teeth of the ratchenwheel H3. Said lever I isifurther provided near'its outerfen'd 'with a finger a,

which extends forward beyond the front ofthey plate A2, and a rearwardlyfprojecting pin b, to

which-is pivotally'connected one end of a link e or pitman J, theA lower end of which link or pitman is pivotally connected withtheupper end of 4thearlnaturel) of the solenoidC.

.With'in the frame below the shaft'His jourf n'aled a'sliaft K, having agear-'wheelK' fixedthereon inmeshwith, the pinion H', and on its forwardend, which projects" ,throughl the plate A2, lis fixed a "pinion YK2, and `secured to" a sleeve L,"dispos ed upon the end' ofv said .shaft K' in fron'tof the pinion K2, vis a gearwheel L', the shaft-K being adapted to receive the 'minute-hand' andthe sleeveL the hourvhand; Upon thefrontof the plate A2 directly "below the shaftK is secured a short shaft M,

uponwhich revolves a gear-'wheel M', inmesh- With-the' pinion K2, and 'aj pinion M2, secured tosaid gear-wheel Mv and meshing .with .the .gear-wheel L.-

' vAbove the shaft l lthe forward end of.' which ei'i't'ends through II isjournaled a shaft the'plat'e AA2 and fis 'adapted to-re'ceive the seconds-liand.l .Upon said shaft Nwithin the frame i'S 'fined a pinion N, ininesh 4with the gear-Wheel H2, and in' frontof said pinion is fixedthe' :scape-wheel N2, .and above said vshaft Nis journaled as'haftO, carryingthe pallet Uvgwhichengages the teeth of 'thascapen rool wheel N2. 4Adjacent to the rear end of the shalt (I) is lixed the upper end ol' the crutch l, the other end of which extends. outward through an opening in the plate A' and its lower forked end embracing the pendulumrod Q, suspended from the endl the pillar B.

The forward end of the shaft O is provided with a head o, of insulating material, upon which is secured a contact-finger R, having a yplatin um tip d, and R' denotes a helical copper conductor having one end secured to the insulated binding-post'frR2 onthe platlA2 and its other en d connected to vfixentact-finger R on the insulating-head c, whereby the currenty is conducted from said binding-post R2 to the:

' contact-ingerf'R.

Upon the front ofthe plate A2 alidvi the shaft K issecured a bracket S, -inwhich is. pivotally `sumiorted adjvacentvrto, its lower end a leverS', which extends diagnallyupwardf across the plate A3, and itslup'per end, whichv is disposed between pins-"e e, projectingdutf, wardly from the plateei, provided-fwith a platinum tip f. 2:,

Freni the hindingposts F and R" extend wires g h, which are connected to the`oppp' site poles 'of a battery. l f l The operation is as follows: ff welissume the apparatus to be in the position illustrated in Figs. l and 2, it simply becomes necessary to set the pendulum' in` motion, whereupon the armature D'within thesolenoid C w-ill descend and carry with it the outer end of the lever I and cause the same to rotate the .shaft ll, and thereby transmit motion to train of gearing. As" the armature D withiuthe solenoid C descends it carries with it.' the le ver l, to tlrevouter endlof whichgthe finger-.11ct ,Y

- end of the leveilSl, buty continues to descends,

, end offthe lever S and cause its upper end to be moved inward-into the path lof the end t of the oscillating contact-finger R audestablish a circuit through the parts (l andf with the first downwardmovement;of the yfree end of said linger R'ai'ter the upper" end of the lever S has been mmfedinward, as aforesaid. As soon as the parts dand f contact a'circuit will be established for. a very brief instant,` which will immediately cause, therefore, the solenoid C to be energized and raise the armature I) to its initial' position and at the` same time restore the lever I to its initial por sition, which is thatillustrated at Figs. l and 2 of the drawings. `llereupon the operation `above described will be repeated. y

The course of the current when the circuit is closed through the contacts e and f is asfollows: from the battery through conductor A2, bracket. ll', hollow core C2, solenoid C, shunt G, conductor E, and through conductor h to battery.

It will of course be understood that the con- 1 l terthe linger (L on the lever I has moved` the lower end'of the lever S" inward and its *pper end into the path of the finger R, and

that as soon as the contact has been made and the circuit completed and the lever I restored to its initial position the upper end of but that a circuit can only be established afthe lever S will again fall back outof the i ,path of the fingerland simultaneously therewith the circuit will be again broken.
